According to one embodiment, a user equipment for use in a mobile communication system is configured to: receive control information including a first field and a second field via a control channel, the first field indicating one of N (N≧2) resource block group (RBG) sets and the second field including a bitmap, wherein each bit of the bitmap is used to indicate whether a corresponding resource block (RB) in the indicated one of the N RBG sets is allocated; interpret the first field and the second field for resource allocation in the control information; and receive data using the control information. An RBG set n (0≦n<N) includes every Nth RBG starting from nth RBG, an RBG includes one or more consecutive RBs, and an RB includes a plurality of consecutive subcarriers.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for a user equipment (UE) operating in a wireless communication system, the method comprising: receiving, by the UE, control information including first information and second information, wherein the first information indicates one of two resource allocation types and the second information includes a bitmap indicating resource allocation; and receiving, by the UE, the data using one or more resource blocks (RBs) allocated by the control information, wherein, if the first information indicates a first resource allocation type of the two resource allocation types, a first bit value of the bitmap indicates whether a corresponding resource block group (RBG) is allocated or not; if the first information indicates a second resource allocation type of the two resource allocation types, the control information includes third information indicating one of N RB sets, and a second bit value of the bitmap indicates whether a corresponding RB is allocated or not in the indicated RB set comprising a plurality of RBGs, a size of RBG is N consecutive RBs, and N is an integer equal to or greater than 2, and wherein the indicated RB set comprises a plurality of RBGs, in which neighboring RBGs are spaced by N−1 RBG(s).
2. The method according to claim 1 , wherein the indicated RB set comprises every N th RBG starting from a predetermined RBG.
3. The method according to claim 1 , wherein the first bit value of the bitmap indicates whether a corresponding resource block group (RBG) is allocated or not in consecutive RBGs.
4. The method according to claim 1 , wherein a number of RBs in each RBG depends on a total number of RBs in a subframe.
5. The method according to claim 1 , wherein a number of the RB sets is the same as a number of RBs in each RBG.
6. A user equipment (UE) operating in a wireless communication system, the UE comprising: a radio frequency (RF) module; and a processor configured to control the RF module, wherein the processor is configured to receive control information including first information and second information, wherein the first information indicates one of two resource allocation types and the second information includes a bitmap indicating resource allocation, and to receive the data using one or more resource blocks (RBs) allocated by the control information, wherein, if the first information indicates a first resource allocation type of the two resource allocation types, a first bit value of the bitmap indicates whether a corresponding resource block group (RBG) is allocated or not; if the first information indicates a second resource allocation type of the two resource allocation types, the control information includes third information indicating one of N RB sets, and a second bit value of the bitmap indicates whether a corresponding RB is allocated or not in the indicated RB set comprising a plurality of RBGs, a size of RBG is N consecutive RBs, and N is an integer equal to or greater than 2, and wherein the indicated RB set comprises a plurality of RBGs, in which neighboring RBGs are spaced by N-1 RBG(s).
7. The UE according to claim 6 , wherein the indicated RB set comprises every N th RBG starting from a predetermined RBG.
8. The UE according to claim 6 , wherein the first bit value of the bitmap indicates whether a corresponding resource block group (RBG) is allocated or not in consecutive RBGs.
9. The UE according to claim 6 , wherein a number of RBs in each RBG depends on a total number of RBs in a subframe.
10. UE according to claim 6 , wherein a number of the RB sets is the same as a number of RBs in each RBG.
